part of why Im not sold on Wilcox is because he made his name as DC for Boise and yes I know Oregon lost to them and him. However the WAC and MW offenses werent the same as the big conferences and the shine isnt there for me. (PS Oregon keeps running over him since then at Tenn, UW and USC)
I can only speak to what he did at USC. It seemed like he wanted more of a "bend, but don't break defense." You can get away with that vs. lesser opponents. But against better offensive teams like Oregon, Stanford, etc. it really doesn't work that well. You are allowing them to get within scoring range or darn close to it before your defense starts making stops. Teams like that are too good offensively and will eventually start scoring. Plus, it doesn't help win the field position battle either.
